The flat method is to directly express the size and reinforcement of structural components according to the overall plan representation method of the plan drawing rules of various components directly on the component layout drawings of various components, and then cooperate with the standard construction details to form a complete set of structural construction drawings.

Chapter 1 Basic Knowledge of Plain Reinforcement
1. The concept of equilibrium
The flat method is to directly express the size and reinforcement of structural components according to the overall plan representation method of the plan drawing rules of various components directly on the component layout drawings of various components, and then cooperate with the standard construction details to form a complete set of structural construction drawings.

3. Levels and symbols of steel bars
H Hot Rolling P Light Circle R with ribs B reinforcement ⅠHPB300 A 6-14 ⅡHRB335 B 6-14 Ⅲ HRB400 C 6-50 ⅣHRB 500 D 6-50
4. The difference between the actual length of steel bars and the designed length
Actual length (leach length center line length) Design length (outsourcing) Measuring difference 2 Design length 1 Actual degree The total weight of steel protection three single steel bars meter-degree burning machine Unit length theoretical weight 1000 Convert mn to m Two outsourcing length one center my length
5. The principle of calculation of steel bar engineering quantity
Calculation of steel arrow engineering quantity The principle of calculating the amount of AH hot lactating steel in HPB300 is to calculate the reinforcement first The total length of the B SP light circle in HRB3 is then multiplied by the unit length 피HRB400 industry c TR ribbed weight obtains total weight,
The calculation formula is IV HRB500 More D B Length of single steel with two net length and ten anchor perimeter length 2. Length of steel bars Ten connection length Ten hook length The net card is the net length of the component —Actual length (length of the center line) Design length (outsourcing) Measuring difference 2 Design length 1 Actual degree The total weight of steel protection three single steel bars meter-degree burning machine Unit length theoretical weight 1000 Convert mn to m Two outsourcing length one center My length nominal diameter/mm single steel bar theoretical weight/(kg/m).
6. Definition of thickness of concrete protective layer
The thickness of the protective layer of concrete refers to the outer edge of the outermost steel bar Distance to concrete surface

8. Link to steel bars
There are three types of steel bar connection: wire bonding, mechanical connection and welding.
Supplement: Rebar refers to straight or disc-shaped steel used for reinforced concrete reinforcement ① Light round steel bars → small steel and disc diagram of ordinary low carbon steel ② Deformed steel bars → Rebars with ribs on the surface usually have 2 longitudinal ribs and transverse movements evenly distributed along the length direction ① Spiral ② Herringbone ③ Crescent
